[AJD] 8 Volt Batteries

[Phil Kelley]

Thanks to all who responded to my inquiry abaout charging an 8 volt battery.
The temporary solution has been to reinstall a 6 volt battery which the
tractor system seems to be charging.  Apparently the PO put in an 8 volt to
be sure it would start on auction day and made no other adjustments to the
regulator etc.
